It’s been a while since my last blog post, and this time it will be fun time with windbg. One of DXC customers has been having problem with instances of their site hang and restart. We at Episerver takes the availability and performance of DXC sites very seriously, therefore I was asked to help diagnosing the problem. It’s something I’d like to do and to learn anyway, so game is on.
The golden standard for looking at the kind of those problems is still the tried and trusted Windbg. With the help from the Managed Services Engineer, I was able to access several memory dumps from the site. Most of them were taken when the site stalled, which is usually the most useful moment because it should contain the most critical piece of information why the stall happened.
